如何为Windows应用商店应用复制WndProc？

Question

这是我尝试在Windows应用商店应用中重建的方法。有没有办法复制它？以下代码是IDENTIVE中的一段示例代码。

protected override void WndProc(ref Message aMessage)
{
    if (aMessage.Msg == TNFCWrapper.WM_NFC_NOTIFY)
    {
        string s = "";
        Int32 wParam = aMessage.WParam.ToInt32();
        switch (wParam)
        {
            case TNFCWrapper.NFC_NDEF_FOUND:
                s = "NFC_NDEF_FOUND  Size = " + aMessage.LParam.ToString();
                break;
            case TNFCWrapper.NFC_DEVICE_CHANGED:
                s = "NFC_DEVICE_CHANGED";
                break;
            case TNFCWrapper.NFC_UNKNOWN_SERVICE:
                s = "NFC_UNKNOWN_SERVICE";
                break;
            case TNFCWrapper.NFC_CONNECTED:
                s = "NFC_CONNECTED";
                break;
            case TNFCWrapper.NFC_DISCONNECTED:
                s = "NFC_DISCONNECTED";
                break;
            case TNFCWrapper.NFC_IDLE:
                s = "NFC_IDLE";
                break;
            default:
                s = "UNKNOWN";
                break;
        }
        System.Diagnostics.Debug.WriteLine(s);

        if (wParam == TNFCWrapper.NFC_DEVICE_CHANGED) DeviceCountLabel.Text = aMessage.LParam.ToString();
        if (wParam == TNFCWrapper.NFC_NDEF_FOUND) ReadNDEF();
    }
